Acceleration and Deceleration
 

Acceleration and Deceleration problem 23


Which of the following statements about uniform or non-uniform motion is correct?


  • For a steady motion, the acceleration is zero.

  • For a uniformly accelerated motion, the acceleration increases steadily with time.

  • When steadily accelerating, the path of a motion increases steadily with time.

  • With uniformly accelerated motion, the acceleration is positive and constant.

  • With uniformly accelerated motion, it is considered that the body will travel four times as long in twice the time.

  • With steady deceleration, the path of a motion decreases with time.

  • When the motion is evenly decreasing, the acceleration decreases evenly with time.

  • When steadily decelerating, the speed of the motion decreases steadily with time.

  • When the motion is accelerated unevenly, the acceleration changes over time.
